About the Presets
(1) DVD LFE80Hz
This is a preset optimized for DVD-Video production. The LFE playback bandwidth is set
up to 80 Hz. When using this preset, we recommend that you use an external device to apply
an LPF (fc=80 Hz, –24 dB/oct) to the LFE master source.
To monitor audio on DVD-Audio or SACD discs, change the LFE level (AMP) and LPF
(LPF1) to 0 dB and THRU, respectively, if necessary.
The LFE output gain on some DVD players and decoders may already be set to +10 dB. To
monitor the output from such devices, change the LFE level (AMP) to 0 dB.
(2) DVD LFE120Hz
This is also a preset optimized for DVD-Video production. This preset is the same as preset
(1) mentioned above, except that the LFE playback bandwidth is set up to 120 Hz. Use this
preset to monitor standard LFE signals recorded on DVD-Video discs that include the
high-end frequency ranges (120 Hz).
(3) Movie LFE80Hz
This preset is the same as preset (1) mentioned above, except that the output level of sur-
round channels is set to –3 dB when the Monitor Matrix mode is 5.1 or 6.1. This preset is
suitable for movie production.
When using this preset, we recommend that you use an external device to apply an LPF
(fc=80 Hz, –24 dB/oct) to the LFE master source.
(4) Movie LFE120Hz
This preset is the same as preset (2) mentioned above, except that the output level of sur-
round channels is set to –3 dB when the Monitor Matrix mode is 5.1 or 6.1. This preset is
suitable for movie production.
(5) Bypass
Use this preset not only for bass management but to bypass all parameters, such as the LFE
level & LPF, surround channel level, etc.
To disable only the bass management, select another preset, then turn off the BASS MAN-
AGEMENT ON/OFF button.
